15 people die every year waiting for a donor
Around 200 people in Northern Ireland are on the transplant waiting list and around 15 people die each year waiting for an organ.
More than two-thirds of people here are not on the organ donor register.
A report by the Public Health Agency revealed that around 56% of people favour changing to a presumed consent system.
A Private Member's Bill is currently going through Stormont which will change legislation to improve the levels of organ donation.
UUP MLA Jo-Anne Dobson favours a 'soft opt-out' approach which will be introduced in Wales in 2015.
Under this, people give their consent for donation unless they indicate their objection, although there is a safeguard that families would still have the final say.
DUP MLA Alastair Ross has launched his own Private Member's Bill. He wants an 'opt-in system' via drivers' licences.
Figures show there have been 3,450 new Northern Ireland residents on the organ donor register since February 11.
